+Workflows are centrally hosted in EED_Solutions/eed_gha_workflows.
 Please check for more details here.
 
+### Docker Publish Workflow Triggering
+
+The Docker publish workflow (`publish_docker.yml`) is triggered automatically in the following cases:
+
+- **On any push to the `main` branch.**
+- **On any tag pushed to the repository that matches semantic versioning (`v*.*.*`).**
+- **When a pull request is opened, synchronized, or reopened and the source branch is named `dev` or `release`.**
+  - Note: The workflow runs for all PRs, but will immediately exit unless the source branch is `dev` or `release`.
+
+This ensures Docker images are only built and published for main releases, version tags, and changes coming from the main development branches.
+
